Specification of Letters Patent.

Patented June 20, 1922.

Application filed April 27, 1920'. Serial No. 377,032.

To all whom it may concern:

Be it known that I, VINCENZO MATRANGA,

. a citizen of Italy, and a resident of the city useful improvements in confectioners inachines, and it pertains more particularly to a machine especially adapted for coating cakes, candies and similar confections.

It is an object of the present invention to provide a new and improved mechanism for subjecting or submerging the confections to be coated in the material with which they are to be coated.

It is another object of the invention to provide a machine in which the confections to be coated are momentarily maintained submerged.

It has been found to be advantageous to move the receptacle in. which the coating material is carried to a position where it will submerge the confections, and it is a further object of the present invention to so construct a machine of this character as to ellicaciously carry out this 0 eration.

It is a still further ob ect of the invention to so construct the device that it may be used on-machines ;as at present employed for the purpose of coating confections.

With the above and other objects in view,

. reference is bad to the accompanying drawings, in which- 7 Figure .1 is a view partly in section and partly in end elevation of the front portion of a machine constructed and arranged in accordance with the present invention;

Fig. 2 is a side elevation of the front portion of said machine;

Fig. 3 is a detail sectional view of the mechanism employed for maintaining the confection submerged within the material with which they are coated;

Fig. 4: is a top plan view artly in section taken on the line 4-4 of ig. 3.

Referring more particularly to the drawings, the mechanism is carried by a suitable framework consisting of vertically disposed 'side stanchions or frames 10 connected by horizontally extendin beams 11. Mounted at suitable points within this framework are shafts 12, and each of said shafts carries ne ar each end thereof, a sprocket wheel 13. Traveling over the sprocket wheels 13 i are chains 14 and these chains 14 form an endless-conveyer by means of which the confections are carried through the machine. At spaced points throughout the length of each of the chains 14 are pins 15, and said pins 15'serve as a support or attaching means for racks 16. These racks 16 are provided with prongs or pointed fingers, said fingers projecting at right angles from a trans versely extending bar 17, and said fingers serve as the means for supporting the confections 18. v

To provide for the driving of the chains or conveyer 14, a motor 20 is suitably posit1oned with respect to the framework of the machine, and through the medium of a. belt 21 which passes around the driving pulley 22 of said motor and the main power pulley 23 of the machine, it will be seen that the necessary power is applied to drive the conveyer or chains 14, since these chains 14 pass into engagement with the sprocket wheel 23 shown in dotted lines at the lower portion of Fig. 2.

Extending transversely of the machine is a shaft 25, and on each end of said shaft 25, is a sprocket 26. Mounted below the shaft 25 is a shaft 27, and upon each end is a third shaft 29, and carried by this shaft 29 are sprocket wheels .30. Passing around the sprocket wheels 26, 28 and 30, at each side of the machine, is a chain 31, and this chain serves the means by which the shafts 27 and 29 are driven from the shaft 25, it being understood that said shaft 25 is driven which the confections are to be coated, and

this receptacle 35 is carried upon a table;

by the chains 14 passing around the sprockets designates a 36. The table 36 is mounted in guideways 37 in the framework in such a manner as to' be capable of vertical 'movement therein.

For imparting vertical movement to the ta-- ble 36, the shaft 27 is provided near each.

of its ends with cams- 38, and these cams are adapted to engage blocks 39 on the bottom face of the table 36 to raise and lower the same as the shaft 27 is rotated.

As shown in Fig. 1, guide-blocks 40 are suitably mounted one on each side of the machine, and mounted in each of these guide blocks in avmanner toprovide for vertical movement, is ashaft 41. This shaft 41 is vprovided with a spiral groove 42, and engagmg said spiral groove 42 and carried by the block 40, is a pin 43. To impart vertical movement to each of the shafts 41, the shaft 29 is provided near eachend, with a cam 44, and each of said cams is adapted to engage the rear of a lever 45, it being under- .stood that there is one lever for each of the cams 44. Each of these levers 45 is pivoted as at 46, to the frame, and each lever 1S adapted toengage at its forward end with its respective vertical shaft 41.

Surrounding each shaft 41 and engaging atits upper end with its respective block 40, is a spring47, the lower end of said spring being secured to the shaft asat 48. The

upper end of the shaft 41 is bent at right angles as indicated by the reference charac-' ter 50, and said right-angular portion 50 is again bent at right angles as at 51, from the outer end of'which the shaft is bent downwardly asindicated by the reference charactor 52, and is bent again at right angles as indicated by the reference character 53.. By this constructiom it will be seen that as the shafts 41 are moved vertically through their respective blocks 40, the shafts'41 will begiven a rotary movement, which movement will cause the shafts to travel in and out of the receptacle as shown by dotted lines in Fig. 4; It is to be understood, however, that the cams 44 will operate in advanceof the cams 38 in such a manner that th right-angular extremity 5301 the shaft its operation. I

the heavy coating material in the receptacle by the engagement of the extremity 53 with the confection carriers 16. The cams 38 now operate to'low'er the table 36 and the cams 44 operate to move the right-angular extension of the shaft 41 out of engagement with the bars 17 of thelcarriers 16 in order that there may be no interference with such movement of the carriers 16 as is occasioned by the operation of the chain conveyor 14, whereby such carriers may pass on to the rear of the machine where they are removed from the conveyor 14. I

By this construction it will be seen that the container for the coating material is. I

rotate if properly timed in such a-manner as to clear the sidesof the receptacle in What is Carma is z 1. suitable support, an endless conveyer traveling through said support, a plurality of con- 41 will engage the cross bar 17 of the confection carrier before the receptacle 35 hasi been moved vertically to the position where the confections are submerged, and said right angular extension 53 is not moved to bination,

the dotted line position in Fig.4 until the v receptacle 35 has been lowered.

.- The device operates inthe following manner:

The operator stands on, theplatform the confection carriers or racks 16 upon the pins 15; as the same present themselves at the front of the machine. The confection in front of'the receptacle 35 and positions carriers 16 are so positioned on the chain conveyor 14' as to be engaged as they move. downwardly by the right-angular extremity 53 of the downwardly movingishaft 41 and move while so engaged without being held against movement occasioned by the operation of the chain conveyor until such time as the cams 38 operate to elevate the table 36 and the receptacle 35 to the position shown in Figure 1, in which position the 'confections18 are submerged, being pre vented from rising independently of actua-= tion by the chain conveyor to the surface of fection-carrying racks carried by said conveyer, a coating-material receptacle, means operated from said conveyor for periodically elevating the coatlng-material receptacle,

and means adaptedfor engagement with the confection-carrying racks for maintaining said racks submerged in the coating material in the receptacle when vated position.
